i know, i know.  if i had done that in the first place this would have been a whole lot easier.  i had to have had an RF switch at one point (from Nintendo) because i had done what i'm trying to do now only with my N64.  but, it's gone.  and if i really want to do this right, i sould buy 2 RF switches.  i tried running everything thru the modulator and back out to the AV swithch and back in to the tv or something, but it didn't work.  i have no clue why though.  in theory, it should work.  maybe it was a faulty wire.  i just used some crappy old cable wire i found in the basement.  i'll figure it out, and i'm not buying anything else, i'm saving all my money for games.  plus, it's all a matter of laziness.  in order to play my N64, all i'd have to do is unplug a couple of things, and plug in a couple more.  I HATE BEING POOR!!!  i want a job
oh yeah, if anything doesn't make sense here, it's becasue of me.  my terminology for this kind of stuff might be way off.  but i'm pretty sure i got it right.
